's prints for the heat guard work pretty well. I had to shave a little more out of the notch on the back for the AC line and the bolt holes had to be adjusted just a bit as well. Overall it looks great. You do need a short piece of 4" pipe to support the filter where the hose clamps down. I went without at first thinking it was strong enough, but it kept slipping loose.
